This Fluency Activity is a part of the Lesson 17, Unit 6, Grade 2. Students practice subtraction in order to gain mastery of the sums and differences within 20 and to see the relationship with larger numbers. After I say a basic fact for you to solve, make a pattern sequence by adding 10 to the whole and then subtracting. Continue until I say to stop.
